Vonoprazan-amoxicillin dual therapy for Helicobacter pylori eradication in Chinese population: A prospective, multicenter, randomized, two-stage study. World J Gastroenterol 2024; 30:3304-3313. [PMID: 39086752 PMCID: PMC11287422 DOI: 10.3748/wjg.v30.i27.3304] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 06/12/2024] [Accepted: 06/25/2024] [Indexed: 07/11/2024] Open
Abstract
BACKGROUND The efficacy of Vonoprazan-amoxicillin dual therapy (VAT) in the treatment of Helicobacter pylori (H. pylori) is controversial. AIM To evaluate the efficacy of VAT in the Chinese population. METHODS This prospective, multicenter, randomized, open-label, and two-stage study was conducted at 23 centers in Fujian, China (May 2021-April 2022). H. pylori-infected patients were randomized to bismuth quadruple therapy (BQT), BQT-Vonoprazan (BQT-V), seven-day VAT (VAT-7), ten-day VAT (VAT-10), and fourteen-day VAT (VAT-14) groups. The primary endpoint was the H. pylori eradication rate. The secondary endpoint was the frequency of adverse events. This study was registered with the Chinese Clinical Trial Registry, ChiCTR2100045778. RESULTS In the first stage, VAT-7 and BQT-V groups were selected for early termination because less than 23 among 28 cases were eradicated. In the second stage, the eradication rates for BQT, VAT-10, and VA-14 were 80.2% [95% confidence interval (95%CI): 71.4%-86.8%], 93.2% (86.6%-96.7%), 92.2% (85.3%-96.0%) in the intention-to-treat (ITT) analysis, and 80.9% (95%CI: 71.7%-87.5%), 94.0% (87.5%-97.2%), and 93.9% (87.4%-97.2%) in the per-protocol analysis. The ITT analysis showed a higher eradication rate in the VAT-10 and VAT-14 groups than in the BQT group (P = 0.022 and P = 0.046, respectively). The incidence of adverse events in the VAT-10 and VAT-14 groups was lower than in the BQT group (25.27% and 13.73% vs 37.62%, respectively; P < 0.001). CONCLUSION VAT with a duration of 10 or 14 days achieves a higher eradication rate than the BQT, with a more tolerable safety profile in H. pylori-infected patients in Fujian.

Eradication rates of Helicobacter pylori in treatment-naive patients following 14-day vonoprazan-amoxicillin dual therapy: A multicenter randomized controlled trial in China. Helicobacter 2023:e12970. [PMID: 37160689 DOI: 10.1111/hel.12970] [Citation(s) in RCA: 20] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 02/26/2023] [Accepted: 03/02/2023] [Indexed: 05/11/2023]
Abstract
BACKGROUND Potassium-competitive acid blockers (P-CAB) are recommended for the treatment of Helicobacter pylori infections, but dual therapy of P-CAB with amoxicillin has been poorly studied. The current study compared the efficacy, adverse reactions, compliance, and effects on gut microbiota of 14-day vonoprazan-amoxicillin (VA) dual therapy with esomeprazole, bismuth potassium citrate, amoxicillin, and metronidazole (EBAM) quadruple therapy in treatment-naive patients with H. pylori. MATERIALS AND METHODS This was a multicenter, open-label, randomized, and controlled, non-inferiority study. Patients (n = 194) enrolled from six centers were randomly divided into either the VA or EBAM group. H. pylori eradication was determined using 13 C urea breath tests (UBT) 4-6 weeks post-treatment. Fecal samples were collected, and gut microbial populations were analyzed by 16S rDNA and metagenomic sequencing technology. RESULTS Eradication rates of H. pylori in the VA and EBAM groups were 88.7% and 91.8%, respectively, according to intention-to-treat (ITT) analysis; 95.6% and 96.7% with per-protocol (PP) analysis; and 94.5% and 96.7% with modified ITT (mITT) analysis (all p > 0.05). The incidence of adverse reactions in the VA group was significantly lower compared to the EBAM group, and compliance within both groups was good. There was no difference in α-diversity or microbial composition in the VA and EBAM groups at one-month post-treatment compared to baseline, except for a markedly reduced abundance of Bacteroides in the EBAM group. CONCLUSION VA therapy achieved excellent eradication rates with low adverse reactions, good compliance, and little impact on gut microbiota. VA therapy should be recommended as a first-line treatment against H. pylori.

Abstract
BACKGROUND & AIMS The decline in Helicobacter pylori cure rates emphasizes the need for readily available methods to determine antimicrobial susceptibility. Our aim was to compare targeted next-generation sequencing (NGS) and culture-based H pylori susceptibility testing using clinical isolates and paired formalin-fixed, paraffin-embedded (FFPE) gastric biopsies. METHODS H pylori isolates and FFPE tissues were tested for susceptibility to amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline, and rifabutin using agar dilution and NGS targeted to 23S rRNA, gyrA, 16S rRNA, pbp1, rpoB and rdxA. Agreement was quantified using κ statistics. RESULTS Paired comparisons included 170 isolates and FFPE tissue for amoxicillin, clarithromycin, metronidazole, and rifabutin and 57 isolates and FFPE tissue for levofloxacin and tetracycline. Agreement between agar dilution and NGS from culture isolates was very good for clarithromycin (κ = 0.90012), good for levofloxacin (κ = 0.78161) and fair for metronidazole (κ = 0.55880), and amoxicillin (κ = 0.21400). Only 1 isolate was resistant to tetracycline (culture) and 1 to rifabutin (NGS). Comparison of NGS from tissue blocks and agar dilution from isolates from the same stomachs demonstrated good accuracy to predict resistance for clarithromycin (94.1%), amoxicillin (95.9%), metronidazole (77%), levofloxacin (87.7%), and tetracycline (98.2%). Lack of resistance precluded comparisons for tetracycline and rifabutin. CONCLUSIONS Compared with agar dilution, NGS reliably determined resistance to clarithromycin, levofloxacin, rifabutin, and tetracycline from clinical isolates and formalin-fixed gastric tissue. Consistency was fair for metronidazole and amoxicillin. Culture-based testing can predict treatment outcomes with clarithromycin and levofloxacin. Studies are needed to compare the relative ability of both methods to predict treatment outcomes for other antibiotics.

Abstract
As antibiotic resistance rates increase, Helicobacter pylori (H. pylori) eradication regimens are constantly being updated. Quadruple therapy with bismuth is currently the main empirical eradication regimen. However, long-term use of multiple antibiotics will enhance the resistance to them. Therefore, there is a need for a new regimen to eliminate H. pylori and reduce antibiotics used to prevent further resistance. High-dose dual therapy (HDDT) with a proton pump inhibitor and amoxicillin may be a breakthrough in eradicating H. pylori. Current research shows that HDDT, as a first-line regimen or rescue regimen, has an eradication rate comparable to quadruple therapy with a low incidence of adverse events, and the use of a single antibiotic greatly reduces the occurrence of antibiotic resistance.

Abstract
AIM The aim of this study was to perform a systematic review and meta-analysis on high-dose dual therapy (HDDT) versus bismuth quadruple therapy (BQT) for Helicobacter pylori infection. METHODS Comparing HDDT to BQT were identified from PubMed, EMBASE, Cochrane library, CNKI, and Wanfang databases in Chinese up to March 2018. Statistical analyses were conducted using Review Manager 5.3 to compare the efficacy and side effects of these 2 therapies for H pylori infection. Dichotomous data were pooled to score the relative risk (RR) with 95% confidence intervals (CIs). RESULTS Four randomized clinical trials (RCTs) including 829 patients with a diagnosis of H pylori infection were assessed. Overall the meta-analysis showed that both HDDT and BQT achieved similar efficacy of intention-to-treat (ITT) eradication rate, 85.5% versus 87.2%, RR 1.01 (95% CI: 0.96-1.06), P = .63, and of per-protocol (PP) eradication rate, 88.4% versus 91.5%, RR 1.00 (95% CI: 0.96-1.04), P = .99, and adherence 97.8% versus 95.0%, RR 1.01 (95% CI: 0.99-1.04), P = .32, but side effects were more likely in BQT (14.4% vs 40.4%, RR 0.42 (95% CI: 0.32-0.54), P <.00001). CONCLUSION Both HDDT and BQT can achieve similar eradication rate for H pylori infection and adherence, and generally HDDT causes fewer side effects.

Abstract
AIM To evaluate the clinical efficacy and safety of high-dose amoxicillin/esomeprazole dual therapy as a first-line therapy for Helicobacter pylori (H. pylori) eradication.
METHODS One hundred and forty-two subjects infected with H. pylori and naive to treatment were randomly assigned to receive either 14-d high-dose amoxicillin/esomeprazole dual therapy (esomeprazole 20 mg and amoxicillin 0.75 g, four times a day; EA group) or bismuth-based quadruple therapy [esomeprazole 20 mg, bismuth potassium citrate 220 mg (elemental bismuth), amoxicillin 1 g, and clarithromycin 0.5 g, twice a day; EBAC group]. Six weeks after treatment, H. pylori eradication was assessed by using the urea breath test (13C or 14C).
RESULTS A total of 131 subjects completed this clinical trial. H. pylori eradication rates by intention-to-treat (ITT) and per-protocol (PP) analysis in the EA group were 82.9% and 89.2%, respectively, and those in the EBAC group were 86.1% and 93.9%, respectively. No significant difference was found in H. pylori eradication rates by both ITT and PP analysis (P > 0.05). The incidence of side effects by PP analysis in the EBAC group was significantly higher than that in the EA group (15.2% vs 3.1%, P < 0.05). All the side effects disappeared after discontinuing the drugs.
CONCLUSION High-dose amoxicillin/esomeprazole dual therapy can be used as an effective and safety first-line therapy for H. pylori infection.

Abstract
OBJECTIVE Although some studies have reported >90% success with high-dose dual proton pump inhibitor (PPI)-amoxicillin dual therapy for Helicobacter pylori (H. pylori) eradication, the efficacy of this therapy remains controversial. We aimed to re-evaluate the efficacy and safety of high-dose dual therapy on H. pylori eradication. METHODS We searched PubMed, the Cochrane Library, and EMBASE for randomized clinical trials (RCTs) evaluating the efficacy of high-dose PPI-amoxicillin dual therapy as the rescue therapy on H. pylori eradication. Treatment effect was determined with a fixed-effect model using the inverse variance method and was expressed as risk ratio (RR) with 95% confidence interval (CI). RESULTS Because of significant statistical heterogeneity (χ2 15.98, I2 = 69%) among the six studies that qualified, four RCTs that included 473 patients with H. pylori infection after eradication failure were assessed. The meta-analysis showed that high-dose dual therapy and guideline-recommended rescue therapies achieved similar efficacy (81.3% vs 81.5%, RR 1.00 [95% CI 0.93-1.08], intention-to-treat analysis), compliance (95.3% vs 95.4%, RR 1.00 [95% CI 0.97-1.03]), and side effects (17.9% vs 19.7%, RR 0.88 [95% CI 0.62-1.25]). CONCLUSIONS High-dose PPI-amoxicillin dual therapy is comparable to recommended rescue therapies for H. pylori infection. More researches are needed to determine the efficacy of high-dose dual therapy as a first-line therapy.

Abstract
In most regions of the world, antimicrobial resistance has increased to the point where empirical standard triple therapy for Helicobacter pylorieradication is no longer recommended. The treatment outcome in a population is calculated as the sum of the treatment success in the subpopulation with susceptible infections plus treatment success in the subpopulation with resistant infections. The addition of bismuth (i.e., 14-day triple therapy plus bismuth) can improve cure rates despite a high prevalence of antimicrobial resistance. The major bismuth effect is to add an additional 30%-40% to the success with resistant infections. The overall result is therefore dependent on the prevalence of resistance and the treatment success in the subpopulation with resistant infections (eg, with proton-pump inhibitor-amoxicillin dual therapy). Here, we explore the contribution of each component and the mechanisms of how bismuth might enhance the effectiveness of triple therapy. We also discuss the limitations of this approach and provide suggestions how triple therapy plus bismuth might be further improved.

Abstract
Helicobacter pylori (H. pylori) is an important major cause of peptic ulcer disease and gastric malignancies such as mucosa-associated lymphoid tissue lymphoma and gastric adenocarcinoma worldwide. H. pylori treatment still remains a challenge, since many determinants for successful therapy are involved such as individual primary or secondary antibiotics resistance, mucosal drug concentration, patient compliance, side-effect profile and cost. While no new drug has been developed, current therapy still relies on different mixture of known antibiotics and anti-secretory agents. A standard triple therapy consisting of two antibiotics and a proton-pump inhibitor proposed as the first-line regimen. Bismuth-containing quadruple treatment, sequential treatment or a non-bismuth quadruple treatment (concomitant) are also an alternative therapy. Levofloxacin containing triple treatment are recommended as rescue treatment for infection of H. pylori after defeat of first-line therapy. The rapid acquisition of antibiotic resistance reduces the effectiveness of any regimens involving these remedies. Therefore, adding probiotic to the medications, developing anti-H. pylori photodynamic or phytomedicine therapy, and achieving a successful H. pylori vaccine may have the promising to present synergistic or additive consequence against H. pylori, because each of them exert different effects.

Abstract
INTRODUCTION Treatment of Helicobacter pylori (H. pylori) infection is paramount for the management of prevalent gastrointestinal disorders and in the prevention of gastric cancer. Due to increasing antimicrobial resistance, performance of standard triple therapies has now declined to unacceptably low levels. AREAS COVERED In this article: i) we critically revise optimization tools aiming to improve the outcome of standard treatments; ii) we provide updated evidence on the efficacy and rationale for the use of several non-bismuth quadruple regimens in clinical practice, recommended as preferred empirical therapies in areas of high clarithromycin resistance. EXPERT OPINION Prolonged (14-day) treatment duration may boost the efficacy of standard triple therapy by approximately 5%. Use of a high-dose PPI and/or new-generation PPIs, rabeprazole and esomeprazole, might improve eradication rates, particularly in regions where the CYP2C19 rapid metabolizer phenotype is prevalent. Adjunctive probiotics may be considered to improve treatment tolerability, though more data are required to better define their role in H. pylori eradication. Among non-bismuth quadruple regimens, both concomitant and sequential therapies are appropriate options for high-resistance settings; however, concomitant therapy appears to be less impaired by dual clarithromycin/metronidazole resistance. Hybrid therapy is a promising new alternative which seems not to be inferior to concomitant therapy.

Abstract
OBJECTIVE To evaluate the eradication rates, side effects and the patient compliance of a dual therapy with rabeprazole and amoxicillin as the first-line therapy in patients with Helicobacter pylori (H. pylori) infection. METHODS A total of 120 patients diagnosed endoscopically with non-ulcer dyspepsia with H. pylori infection were randomly assigned into two groups, one treated with amoxicillin 1 g thrice daily plus rabeprazole 10 mg twice daily (R10A group) or 20 mg twice daily (R20A group) for 14 days. H. pylori eradication was evaluated by (13) C-urea breath test (UBT) at 4-6 weeks after the completion of treatment. H. pylori eradication rate was analyzed by per-protocol (PP) and intention-to-treat (ITT) analyses together with 95% confidence interval (CI). Side effects and patients' compliance were also recorded. RESULTS Overall, 117 patients (58 in the R10A group and 59 in the R20A group) completed the study, among whom five did not undertake the UBT. H. pylori eradication was achieved in 89.8% of patients in the R20A group by ITT analysis and 93.0% by PP analysis, which was significantly higher than those in the R10A group (75.9% and 80.0%, respectively, P < 0.05). Side effects, including skin rash, abdominal discomfort, headache, insomnia and nausea, were all mild and were treated symptomatically without the need to discontinue the treatment. CONCLUSION The modified dual therapy with high doses of rabeprazole and amoxicillin is considered an effective and safe primary therapy for H. pylori eradication and could be recommended as the first-line eradication regimen for certain patients.

Abstract
BACKGROUND Helicobacter pylori infections have become increasingly difficult to treat. AIM To examine whether amoxicillin and high-dose dexlansoprazole would reliably achieve an H. pylori eradication rate of ≥90%. METHODS An open-label prospective pilot study of H. pylori eradication in treatment-naïve subjects with active H. pylori infection (positive by two tests). THERAPY amoxicillin 1 g and dexlansoprazole 120 mg each twice a day at approximately 12-hour intervals for 14 days. Success was accessed by urea breath test. An effective therapy was defined as a per-protocol treatment success of 90% or greater; treatment success of 80% or less was prespecified as an unacceptable result. RESULTS After 13 subjects were entered (12 men, one woman; average age of 54 years), the prespecified stopping rule of six treatment failures was achieved (i.e., the 95% confidence interval excluded achieving the required 90% success rate even if the proposed study of 50 completed patients were entered) and enrollment was stopped. Per-protocol and intention-to-treat treatment success were both 53.8%; (7/13); 95% CI = 25-80%. Compliance was 100%. Three patients (23%) reported side effects, all of which were mild and none interrupted therapy. CONCLUSION Theoretically, dual PPI plus amoxicillin should reliably eradicate H. pylori provided nearly neutral intragastric pH can be maintained. Clearly, dexlansoprazole, despite being administered at high dose and twice a day (i.e., total daily dose 240 mg), failed to achieve an intragastric milieu consistent with dual PPI plus amoxicillin therapy being an effective anti-H. pylori regimen.

Abstract
OBJECTIVE Standard triple therapy for Helicobacter pylori eradication is no longer effective as an empiric choice in most areas. Even in low clarithromycin resistance areas, results ≥95% are infrequently achieved. This study was designed to search for a version of standard triple therapy for use low prevalence areas or as tailored therapy that is highly effective irrespective of CYP2C19 genotype. DESIGN Two prospective pilot single center studies were performed in Thailand. H. pylori-infected subjects were randomized to 7- or 14-day regimens using a high-dose proton pump inhibitor (PPI) triple therapy consisting of lansoprazole (60 mg) twice daily, amoxicillin 1 g twice daily, and long-acting clarithromycin MR 1 g once daily. H. pylori was defined as positive H. pylori culture; or two positive tests (rapid urease test and histology); CYP2C19 genotyping was performed. H. pylori eradication was evaluated by (13) C-UBT 4 or more weeks after treatment. RESULTS Hundred and ten subjects were enrolled (55 each to the 7- and 14-day regimens). Antibiotic susceptibility testing (25 strains) showed 40% metronidazole resistance but no clarithromycin resistance. CYP2C19 genotyping (64 subjects) revealed 56.3% rapid metabolizer, 29.7% intermediate metabolizer, and 14% poor metabolizer. The eradication rate with the 14-day regimen was 100% (95% CI = 93.5-100%) and 92.7% (95% CI = 82-97%) with the 7-day regimen. The difference was related to improved eradication at 14 days in rapid metabolizers (i.e. 100 vs 88.2%). CONCLUSION Triple therapy using a 14-day high-dose PPI and long-acting clarithromycin provided an excellent cure rate (100%) regardless of the CYP2C19 genotype.

Abstract
BACKGROUND Penicillins inhibit cell wall synthesis; therefore, Helicobacter pylori must be dividing for this class of antibiotics to be effective in eradication therapy. Identifying growth responses to varying medium pH may allow design of more effective treatment regimens. AIM To determine the effects of acidity on bacterial growth and the bactericidal efficacy of ampicillin. METHODS H. pylori were incubated in dialysis chambers suspended in 1.5-L of media at various pHs with 5 mM urea, with or without ampicillin, for 4, 8 or 16 h, thus mimicking unbuffered gastric juice. Changes in gene expression, viability and survival were determined. RESULTS At pH 3.0, but not at pH 4.5 or 7.4, there was decreased expression of ~400 genes, including many cell envelope biosynthesis, cell division and penicillin-binding protein genes. Ampicillin was bactericidal at pH 4.5 and 7.4, but not at pH 3.0. CONCLUSIONS Ampicillin is bactericidal at pH 4.5 and 7.4, but not at pH 3.0, due to decreased expression of cell envelope and division genes with loss of cell division at pH 3.0. Therefore, at pH 3.0, the likely pH at the gastric surface, the bacteria are nondividing and persist with ampicillin treatment. A more effective inhibitor of acid secretion that maintains gastric pH near neutrality for 24 h/day should enhance the efficacy of amoxicillin, improving triple therapy and likely even allowing dual amoxicillin-based therapy for H. pylori eradication.

Abstract
Background. Though Helicobacter pylori (HP) infections have progressively declined throughout most of the industrialized countries, a gradual increase in failure of HP eradication treatments is observed. Aim. To critically review evidence on the efficacy of the therapeutic availabilities for HP eradication, as yet. Methods. A selection of Clinical Trials, Systematic Reviews and Meta-analyses within the time period 2010–2012, was performed through a Medline search. Previous references were included when basically supporting the first selection. Results. An increasing rise in HP resistance rates for antimicrobial agents is currently observed. Further causes of HP treatment failure include polymorphisms of the CYP 2C19, an increased body mass index (BMI), smoking, poor compliance and re-infections. Alternative recent approaches to standard triple therapy have been attempted to increase the eradication rate, including bismuth-containing quadruple therapy, non-bismuth containing quadruple therapy, sequential therapy and levofloxacin-containing regimens. Conclusions. The main current aims should be the maintenance of a high eradication rate (>85%) of HP and the prevention of any increase in antimicrobial resistance. In the next future, the perspective of a tailored therapy could optimize eradication regimens within the different countries.
